I have been using the firmware file for more than a year without any
problems on 3.14.23, so I assume it is v1. I don't know why the driver
tells me it's v2, however. Maybe my tree is messed up.
If I port adau1701.{c,h} and sigmadsp.{c,h} from 3.14.23 to 3.18.3, it
works. I think I have to look deeper into that...

If I cherry-pick that in, the message is gone, but still, I don't have
no output.
